    Resolved [RESOLVED] Scanner sufix prefix to change language.

    Hi.
    We have a ds6878 Zerba - Motorola scanner.
    We are trying to set a default language by using ascii commands.
    Is this possible?
    For example we have set code 5001 so the scanner can press "F1" before the scan.
    Currently we have a problem because a user can press alt + shift by mistake and scan in Greek and that will be a problem.
    Of course the most common idea would be to disable Greek from keyboard but some machines use other applications that need Greek characters, so we cannot disable Greek from every PC.
    So is there an ascii way to somehow default to English? Probably not but just checking.
    Thanks.

    Edit.
    We can also use these commands :https://www.sciencebuddies.org/scien...haracter-codes
    From an internal program we use. If there is any chance. But we can use only 2 commands (command1 -- command2)

    Edit2. I'm attaching all the commands...

    Re: Scanner sufix prefix to change language.

    alt + shift by mistake and scan in Greek
    Not sure I understand the problem. The usual way to prevent Greek (or other) unwanted characters from being scanned is to not scan bar codes that have those characters. If the scanner is being used with a keyboard wedge interface, then there is no way to affect the characters being scanned without also affecting the characters that can be entered using the keyboard.

    Re: Scanner sufix prefix to change language.

    Hmm.
    Now I too do not understand what you're saying.
    If I have a QRCODE in English and I press alt+shift (that is the Greek change combination) and scan, it will show Greek Chars.
    I read of a way for the messaging toolking Qrcode Encoder to see only English by setting the ANSI version to 437 but that does not seem to have any effect on the Qrcode
    (set by using the kit and doing qrcoder.encode("text",437)

    Re: Scanner sufix prefix to change language.

    Post the ASCII values of the data you are scanning, with and without the "Alt+Shift" switching in effect.

    It sounds like you already have translation software installed that is converting your data after it is typed/scanned.

    Re: Scanner sufix prefix to change language.

    Hello.
    The Value is english and turns to Greek when we alt+shift.
    What Zebra scanner do is "typing" the scanned values.
    I'm searching for a why for the scanner not to "alt+shift"

    Re: Scanner sufix prefix to change language.

    We had another idea.
    We tried to use a default keyboard shortcut that turns to English (ctrl 6) .
    Now the problem is that the damn scanner does not accept multiple commands. We need a ctrl + 6 and after that an F1 .
    It will not do that.
    I have searched the entire net for multiple commands on the specific scanner and I cannot find something.\
    I try with a "prefix" command "prefix "command" and it does not work.
    I try with "prefix" "command" "command" ...nada.

    Re: Scanner sufix prefix to change language.

    I am still somewhat confused on what is actually happening. It sounds like you are using a custom keyboard of some sort, since the Alt commands only seem to work on data entered using the keyboard.

    Nevertheless, the scanner Prefix assignment should be able to hold more than one character, since the default is <cr><lf> according to the user manual. To enter the values, you scan the proper codes from the user manual. If you have not already downloaded the manual, you should do so now and read through it.

    Re: Scanner sufix prefix to change language.

    No custom keyboard. But we have Greek language here that changes with alt + shift
    I have the manual.
    It states:
    <Prefix><DATA><SUFFIX 1>
    Scan Prefix
    5
    0
    0
    1 ---This is the f1 key
    Scan Suffix 1
    ENTER

    The ctrl 06 keys is
    1
    0
    3
    0

    So I scan either using:
    <Prefix><DATA><SUFFIX 1>
    Scan Prefix
    5
    0
    0
    1
    ------Here it beeps like an "OK" signal
    1 ----beeps like not understanding the command
    0 ----beeps like not understanding the command
    3 ----beeps like not understanding the command
    0 ----beeps like not understanding the command

    Scan Suffix 1
    ENTER

    This maintains the F1 only.



    The ctrl 06 keys is
    1
    0
    3
    0

    So I scan either using:
    <Prefix><DATA><SUFFIX 1>
    Scan Prefix
    5
    0
    0
    1
    Scan Prefix
    1
    0
    3
    0
    Scan Suffix 1
    ENTER

    ----Again just f1 command.
    If I scan opposite (1030 and then 5001) it will understand just the ctrl 6 command. So the commands work but they cannot be combined.
    How would I go and combine them if you say that it can be done?
    The manual does not state anything like this.

    Re: Scanner sufix prefix to change language.

    Fromthe manual:
    Scan Data Transmission Format
    Parameter # 235
    To change the scan data format, scan one of the following eight bar codes corresponding to the desired format.
    To set values for the prefix and/or suffix, see Prefix/Suffix Values on page 5-48.
    NOTE If using this parameter do not use ADF rules to set the prefix/suffix.
    *Data As Is
    (0)
    <DATA> <SUFFIX 1>
    (1)
    <DATA> <SUFFIX 2>
    (2)
    <DATA> <SUFFIX 1> <SUFFIX 2>
    (3)
    <PREFIX> <DATA >
    (4)
    Scan Data Transmission Format (continued)
    <PREFIX> <DATA> <SUFFIX 1>
    (5)
    <PREFIX> <DATA> <SUFFIX 2>
    (6)
    <PREFIX> <DATA> <SUFFIX 1> <SUFFIX 2>
    (7)
    FN1 Substitution Values
    Key Category Parameter # 103
    Decimal Value Parameter # 109
    The Wedge and USB Keyboard (HID) hosts support a FN1 Substitution feature. Enabling this substitutes any
    FN1 character (0x1b) in an EAN128 bar code with a value. This value defaults to 7013 (Enter Key).
    When using host commands to set the FN1 substitution value, set the key category parameter to 1, then set
    the 3-digit keystroke value. See the ASCII Character Set table for the current host interface for the desired
    value.
    To select a FN1 substitution value via bar code menus:
    1. Scan the bar code below.
    2. Locate the keystroke desired for FN1 Substitution in the ASCII Character Set table for the current host
    interface. Enter the 4-digit ASCII Value by scanning each digit in Appendix D, Numeric Bar Codes.
    To correct an error or change the selection, scan Cancel.
    To enable FN1 substitution for USB Keyboard (HID), scan the Enable FN1 Substitution bar code on page
    5-50.

    Re: Scanner sufix prefix to change language.

    It might be time to check with Zebra to see if you are really limited to just one character for prefix and/or suffix codes.

    Alternative ideas:

    Set the keyboard mode the way you want it and disable changes while the scanner is in use.

    Use something like SerialMagic from SerialIO.com to add prefix/suffix characters. That software does allow multiple character prefix and suffix codes.

    Re: Scanner sufix prefix to change language.

    For setting the keyboards and disable changes, I must maintain some code. That is not a preferred solution.
    SerialMagic need money and I don't think we could get a budget for something this small.
    It's either removing Greek from keyboard or contact Zebra.

    P.S. Manual is public an is here:
    https://www.zebra.com/us/en/support-...ds6878-dl.html
    There is an advance manual rules here: https://www.zebra.com/content/dam/ze...de-a-en-us.pdf
    This is very complex I'm reading it but its very confusing.



    EDIT:

    FIXED!FIXED!
    You need the advanced programming guide to program a rule with keys!
    You need to Add a new rule, send ctrl + 6, send F1 , Send data that remains, send Enter key and save the rule.
    Damn!

    P.S. I tried to scan a Code Pages that only supports English (for example 437) but when switching to Greek keyboard we are getting characters back, and if unknown then we get the unknown. I would much prefer to do that instead of the ctrl + 6 fix but i do not think that it is possible. Or I am scanning a wrong codepage...

    Re: [RESOLVED] Scanner sufix prefix to change language.

    Thanks for the update, and the link to the advanced programming manual for the scanner. I thought that the Symbol/Zebra scanners should have the capability needed.

    Your basic issue is that your users are using the keyboard software to interfere with the scanner data. The computer does not know that the data came from the scanner rather than the keyboard, and so it allows the unwanted changes. You could change to some better users, but that probably isn't going to happen, so Prefix and Suffix codes from the scanner is the next best fix. Changing the scanner to English doesn't work because the keyboard software gets to the data after the scanner has sent it.
